The body of the second-generation A4 has increased compared to its predecessor: by 69 mm in length (4547 mm), width by 33 mm (1766 mm), and 13 mm in height.
A4 is equipped with a full range of safety features. The basis for the safety of passengers is a solid cabin section with certain deformation characteristics. Safety features also include airbags for the driver and front passenger, as well as Sideguard head airbags and belt tensioners for the front seats. Electronic anti-skid system fitted as standard (stability control), as well as an emergency brake booster.
The fully galvanized body, with a 10-year anti-corrosion guarantee, is a load-bearing steel structure with integrated aluminum components to reduce vehicle weight. High-strength steel sheets, plastics and magnesium are used as materials to further reduce the weight of the car.
Gasoline engines - in-line four-cylinder or V-shaped six-cylinder (eight-cylinder on S4 models) with electronic control.
Diesel engines - in-line four-cylinder or V-shaped six-cylinder.
All engines are water-cooled and located in the engine compartment along the vehicle.
Models available with front or all-wheel drive «Quattro». On all-wheel drive models, a center differential is installed «Torsen» with automatic lock.
The modified aluminum alloy chassis provides high dynamic performance and driving precision.
Depending on the configuration, a fully synchronized 5- or 6-speed manual transmission or AT is installed (Tiptronic with DSP dynamic control program or Multitronic with DPR dynamic control program).
Front suspension - independent, four-link McPherson with coil springs, telescopic gas-filled shock absorbers and a tubular stabilizer bar. The bridge beam is attached to the body on rubber-metal supports.
Independent rear wheel suspension with coil springs and gas-filled shock absorbers. The bridge beam is attached to the body on rubber-metal supports.
Steering gear - rack and pinion, with speed-dependent power steering gain (Servotronic). Adjustable, safety steering column.
The car is equipped with an electronic anti-skid system (stability stabilization - ESP), integrating the anti-lock brake system (ABS), traction control (ASR), electronic differential lock (EDS) and brake force distributor (EBV) into a single network. Emergency brake booster installed (BAS).
The basic brake system is hydraulic, dual-circuit with diagonal separation and dual booster. Anti-lock brake system (ABS) with electronic brake force distribution (EBV) with vacuum booster.
Brakes - disc, ventilated on the front wheels.
For locking the locks, a single lock with direct or remote control is used.
The next scheduled maintenance date is indicated by an indicator on the display.
The driver information system is installed as standard equipment.
Excellent aerodynamics and the use of lightweight materials contributed to lower fuel consumption. Thanks to the use of high-strength steel and additional protective elements, as well as the development of large deformation zones, it provides even greater safety than the previous model.
